HAND-REST.

Application filed January 13, 1908.

T 0 all whom it may concern:

Be it known that I, l/VILLIAM FLATTERY, a citizen of the United States, residing at Germantown, a suburb of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Hand-Rests, of which the following is a specification.

This invention relates to hand rests for penmens use, the object being to provide a rest especially adapted to be used by free hand penmen, whereby the hand will be supported in such a manner that it can move easily over the writing surface, so as to avoid cramping of the hand caused by continuous writing.

Another object of my invention is to provide a hand rest which is so shaped that it will fit snugly over the joint of the metacarpal bone of the little finger, and the pisiform bone of the carpus or wrist, so as to protect the same, the hand rest being held in position by an elastic band, which extends around the wrist.

Another object of my invention is to provide a hand rest which is formed of aluminium, having a boss on its convex surface, in which is mounted an anti-friction ball adapted to travel on the writing surface.

These objects are obtained by the novel arrangement and construction of parts hereinafter fully described and shown in the accompanying drawings, in which:

Figure 1, is a perspective view of my improved hand rest, showing it applied to the hand, and, Fig. 2, is a section through the hand rest detached.

In the drawings A, indicates the oval concavo-convex body of my improved hand rest, which is preferably formed of aluminium, having a concavity shaped to fit snugly over the joint of the metacarpal bone of the little finger, and the pisiform bone of the wrist.

The body is provided with oppositely disposed openings A, adjacent its edges, which are cut away as shown at A, in which are adapted to fit the hooks B, secured to the ends of the elastic band C, which extends around the wrist, and holds the rest in position. It will be readily seen by detaching Specification of Letters Patent.

Serial No. 410,531.

one of the hooks, the rest can be readily re- I moved.

A boss D, is formed on the convex surface of the rest to one side of its center, which is provided with a central bore, extending through to the concavity of the rest, in which is adapted to be placed a ball bearing E, the edges of the bore on the face of the boss are contracted so as to prevent the ball from dropping out, and after the ball has been placed therein, a rivet or suitable plug F, is placed in the ball from the inside of the rest, so as to lock the ball therein.

In use the rest is secured on the hand as clearly shown in Fig. 1, and the hand is turned so as to allow the ball to engage the writing surface, which is the proper position for holding the hand in writing, and it will be seen as the hand is moved to form the character in writing, the rest forms a support for the hand, and allows it to move freely.

From the foregoing description it will be seen that I have provided a hand rest which is exceedingly simple and cheap in construction, and one which, will prevent pen paralysis, as in free hand writing the "hand is little finger and ring finger gliding over the surface, and when the writer is compelled to write all day in this manner, the hand becomes cramped, so that it soon becomes impossible to write at all.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A hand rest comprising a concavo-convex body, provided. with oppositely disposed openings and grooves, a boss formed on the convex surface of the body, an anti-friction ball mounted in said boss, and an elastic band provided with hooks, adapted to fit in the openings and grooves of the body for securing said body on the hand.

2. A hand rest comprising an oval concavo-convex body, provided with oppositely disposed openings, adjacent the side edges, a boss formed on the convex surface of the body to one side of the center, provided with p a bore extending through said body, an antifriction. ball arranged in said. bore, a plug senot supposed to touch the paper at all, the

cured in said bore from the inner side of said In testimony whereof I have signed my body for securing said ball in place, and an name to this specification in the presence of elastic band adapted to extend around the two subscribing Witnesses.
